Abstract
We evaluated the safety and efficacy of 120W potassium-titanyl-phosphate (KTP) laser vaporization on patients with non-muscle invasive bladder cancer compared with standard transurethral resection of bladder tumor (TUR-BT). One hundred and fifty-eight patients of non-muscle invasive bladder cancer who underwent either 120W potassium-titanyl-phosphate (KTP) laser vaporization (HPS group, n=74) or transurethral resection of the bladder tumor (TUR-BT group, n=84) were analyzed respectively. The preoperative, intraoperative and postoperative clinical data were recorded and compared in two groups. All patients were successfully treated with 120W-KTP laser vaporization or TUR-BT. No significant differences were observed in operative time, perioperative and postoperative serum sodium and hemoglobin levels between two groups. Importantly, HPS had less specific side effects of TURBT, such as obturator nerve reflex, postoperative bladder irrigation and catheterization time, which shows statistic difference significantly (p< 0.05). Recurrence rate was lower in HPS group than those in TUR-BT group. The 120W-HPS KTP laser as a safe and feasible procedure provids an alternative for the patients with non-muscle invasive bladder cancer, especially for those on anticoagulation therapy.
